Mars Polar Lander Mission Status

March 15, 1999

The Mars Polar Lander has successfully completed its second
course correction to refine its flight path to the red planet.
At 5:05 a.m. Pacific time today, the spacecraft fired its four
maneuvering jets for just under 10 seconds changing its speed by
a mere 0.89 meter per second (2.0 miles per hour).

The spacecraft's next maneuver is scheduled for September 1,
when its flight path will be targeted for a specific landing zone
near the planet's south pole. Observations of the south polar
region by instruments onboard the currently orbiting Mars Global
Surveyor will be used to pick a safe landing spot.

Mars Polar Lander is now 16,510,000 kilometers
(10,070,000 miles) from Earth, traveling at a speed of 1,680
meters per second (3,700 miles per hour). The spacecraft will
land on Mars on December 3, 1999.
